Discussion Overview

This thread discusses various recent developments and information in the field of aerospace, including upcoming launches, scientific missions, and discoveries related to space exploration. The scope includes theoretical insights, technical details, and observational data from missions such as SpaceX Dragon, NASA's Juno, and others.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • Some participants share links to upcoming SpaceX launches and express interest in following the events.
  • There is mention of a digital tape recovered from the Columbia crash that contains footage of reentry plasma flashes, with requests for information on where to view it.
  • Discussion includes a write-up on the K2 mission and its discoveries regarding exoplanets.
  • Participants highlight the significance of NASA's Juno mission to Jupiter, which aims to study the Great Red Spot and its heat dynamics.
  • There is mention of an anomaly in star formation related to the object CX330, which is located in a star-forming region but lacks the typical surrounding gas and dust.
  • Some participants express optimism about government cooperation with private industries in advancing space technology.
  • Information is shared regarding Io's fluctuating atmosphere and the TESS mission's goals in exoplanet exploration.

Areas of Agreement / Disagreement

Participants express a range of views on the significance of recent developments, with some showing enthusiasm for collaborative efforts in space exploration while others raise questions about specific scientific phenomena. No consensus is reached on the implications of the discussed topics.

Contextual Notes

Some discussions involve complex scientific theories and observations that may depend on specific definitions or assumptions, which remain unresolved. The implications of certain findings are also not fully explored.

The abort system might do that (with some rounding errors), but the rocket will certainly not. Net acceleration at liftoff is only something like 0.4 g.

Fueling of Artemis II has started, 9 hours and 50 minutes to go. I started a thread.

Ehh? I don' think so, that's more than 12 g's including the one they already have. I'm not sure where they get that, but it's in the google ai result. Chicken or egg...
That article now contains a more realistic acceleration (around speed of sound after a minute) and the following at the end:
Correction: A previous version of this story misstated the initial liftoff speed of the rocket.

Both stages for the next Starship launch have been moved to the launch site for testing. Looks like a spin prime test of the ship - like a static fire test but without igniting the engine.
Things look on track for an early May launch or so.

The third New Glenn launch is scheduled for April 16. SpaceX has reused boosters hundreds of times. This will be the first time someone else reuses a booster for an orbital rocket.

Tianlong-3 is another rocket designed with a reusable booster. It recently made its first intentional flight, but failed to reach orbit (no recovery attempt yet). It made an accidental flight two years ago.
